Knight & Hale's Tuskarora Hog Grunter uses the Blasting Chamber to chamber and focus the air to provide loud, realistic grunts. The Tuskarora makes the feeding, communal and breeding grunts that trigger the social curiosity, mating anticipation and herd instincts of wild hogs. It's also easy to use by blowing softly into the Blasting Chamber. The flexible collapsible hose allows for manipulation of the sound.
